The remaining possibility was over-heating or burning of the forging, which classically results in large grain size, intergranular fractures, and fine oxide particles dispersed throughout the grains. The induction-heating stress-improvement process was suspected to have...

... Abstract The metallurgical condition of a cylindrical induction melter (CIM) vessel was evaluated after approximately 375 h of operation over a two-year span at temperatures between 1400 to 1500 deg C. Wall thinning and significant grain growth was observed in the lower portion of the conical...

... for dendritic solidification. In welds where cooling rates are very high, dendrite arm spacing is often found to be in the order of 10 μm or more. Here, however, spacing is much narrower, albeit cooling rates were definitely lower in the inductively bent pipes than in most welds. Hence it is suspected that what...
